Application filed July 25, 1910. Serial No. 573,615.

whom it may concern:

it known that I, JAMES MURPHY, a onhicct of the King of Great Britain and .nd, residing at 69 Galloway road, herds Bush, London, W., England, enhave invented certain new and usemprovements in and Relating to Bottleng Machines, of which the following specification. l. This invention relates to bottle blowing lines and has for its object to provide a machine of simple construction.

According to the invention I provide the glass blowing machine with two alternately pcrating and inversely disposed parison molds for each vertically disposed finishing mold. so that one of the parison molds is cooled while t1 other is in operation.

According to the invention moreover I provide two alternately operating bottom molds for each finishing mold said bottom molds being alternately and automatically brought into operation.

.According to the invention moreover 1 provide a head or neck mold intermediate oi the finishing mold and the parison molds and. I rotatibly mount the vertically disposed finishing mold, the inversely disposed parison molds and the head or neck mold upon a vertical shaft which serves simultaneously as the fulcrum for the finishing mold and the parison molds.

The invention is illustrat d in the accompanying' drawings which represent -a machine constructed according to the invention.

Fig. 17 is a plan View of the bottom molds and their operating gear. Figs. 1822 show diagrammatically the various positions of the head or neck mold and the hand levers for operating the same.

In carrying the invention into eiiect I provide upon a frame 1 a vertically disposed shaft 2 which is adapted to support and act as fulcrum for all the molds. In the frame I provide a compressed. air cylinder 3, the piston rod 4 of which is provided on both sides with rackteeth 5 and is mounted at its free 80 end. inhearings 6 in the frame. In the frame I also mount a trip lever 7 adapted to operate the inlet and outlet valves of the compressed air cylinder 3 and I provide means to adjust the said trip' lever 7 in any required position, such for example as a pawl. 8. On each side of the toothed .por tion 5 of the piston rodI provide a vertically disposed shaft 9 and 9 upon each of whichis keyed a toothed wheel H gearing. with the racks Upon these shafts I also provide two sets of toothed Wheels 10 and 11 and 10 and 11* one set 10 and 10 adapted to engage with corresponding toothed wheels 12 mounted in the carrier arms 13 of the finishing mold, and the other set 11 and 11 adapted to engage with toothed wheels 14 mounted on thecarrier arms 15 of the parison molds.

When in. the position shown in Fig. 1

compressed air is admitted to the cylinder 3 at the rear of the piston the piston is moved against the action. of a spring 16 and through the medium of its toothed piston rod 1 and the toothed wheels ll rotates the vertical shalts S) and 9 through an angle of 90 and thus also the carrier arms 13 and 15 of the finishing and parison molds so that the molds, which each consists of two parts, are

opened. 3 It on the operation of the trip latter is moved rearward and the molds are closed.

The two parts of the'vertically disposed finishing molds A are connected to the carrier arms 13 by means of U-shaped frames 17 which are adjustably secured to the carrier arms by bolts 18 mounted in lateral slots provided in the carrier arms. Through the ends of the U-shaped frames 17 pass bolts 19 provided with axial holes through which pass bolts 20 on which the mold parts are mounted so that they ,can be adjusted in a vertical direction. The adjustment of the finishing mold parts is effected by means of lateral screws 21. which contact with the sides of the said mold parts.

The carrier arms 15 for the parison molds are provided at their ends with vertically disposed bolts 22 on which are pivoted two levers 23, each provided with three branches. At the opposite ends of each of the triple branched levers are mounted, in a similar manner to the finishing mold parts, the halves of one of the parison molds B, C. The central arms of the triple branch levers are connected by means of rods 24 to a stationary pivot 25 disposed in front of the vertical shaft 2 upon which the carrier arms 15 are mounted.

In the position shown in Fig. 6 the pari son mold B, that is 'the halves thereof, are brought together. If the carrier arms 15 are moved outward by the rotationof the shafts 9 and 9 then the two halves of the parison mold are separated. These aresimultaneously moved slightly to the rear 9 and 10) for alternately on the carrier arms, as the fulcrum of the rods 2a is in advance of the fulcrum of the carrier arms 15 and thus moves the point of connection of the lovers 23 and thesrods 2 1 slightly behind a line passing through the fulcrum of the levers and the rods.

When the shafts 9 and 9 are rotated in a reverse direction by the piston, the rods and the arms of the branched levers 23 connected thereto are moved to the rear and outward through an angle of 180. In consequence of this the halves of a cool second parison mold C are brought into the operative position while the halves of the hot parison mold B are moved outward and allowed to cool. On the further operation of the machine this procedure is repeated, with the exception that now the parts of the parison mold B are moved toward one another and those of the parison mold C away from one another. It will be understood that the rotation of the mold halves is always in the same direction.

In a modified form of construction (Figs.

bringing the perison molds into the operative and cooling positions two forked arms 15 and 15 are also the movement to the position of the mounted on the vertical shaft 2 and at the ends of the forked arms are rovided the halves of the parison molds B, .J. On opening the mold B the other mold C is closed and on rotating the whole through an angle of 180 the closed mold C is brought into the operative position.

The head or neck mold D (Figs. 1115) is provided at the end of an angular lever cast integral with a compressed air cylinder 31 which is adapted to rotate in a sleeve 32 carried by a bracket mounted upon the vertical shaft 2. The head or neck mold D is composed of two parts which are moved toward or away from one another on inclined'arms 30. This movement for o ening and closing the head or neck mol as of the head or neck mold through an angle of 180 is effected by the operation of a handle 33 provided at the end of the inclined arm 30. This handle is forked and between its prongs 34 is pro vided a pin 35 on which it is adapted to rotate through an angle of 180 about a sleeve 36 mounted at the end of the arm 30.

The prongs 34 of the handle are connected to the front half of the neck or head mold D by short rods 37 and to the rear half of the neck mold by long rods 88. If the handle (Fig. 13) is moved from its lowest position to its highest position the short rods 37 draw the front half of the neck or head mold forward and the long rods 38 push the rear half of the neck or head mold rearward thus opening the head or neck mold.

The piston 39 in the compressed air cylinder 3] for the head or neck mold is provided with an eccentrirally disposed piston rod 40 of which the part projecting into the head or neck mold is formed as a rack -11 adapted to engage with a toothed part 42 of the screw plunger 43 provided in the head or neck mold. The central part of the plunger i s provided with a screw thread 44 of the same pitch as a tap 45 which is to form the screw thread in the bottle neck and is adapted to screw into a lead or guide screw thread 46 in the neck or head mold. The piston 39 in the cylinder therefore rotates the tap 45 into and out of the neck or head producing portion of the head or neck mold on reciprocation.

Through the center of the compressed air cylinder 31 for the head or neck mold passes a tube 47 which is rigidly connected to a supply pipe 48 and cannot therefore rotate with the cylinder 31. The tube 47 is provided with a radial hole 49 which according cylinder is adapted to correspond with an aperture 50 in the cylinder cover 51. The tube 47 passes tightly through the'piston 39 and projects into a hollow in the cylinder base -52 to which is connected the air conduit 53 leadthe cylinder base 52 through which air' ing to the neck 'or head mold. This conduit is provided with-a cock 54 which is operated by a rod and a handle'56 pivoted to the handle 33 for operating the head or neck mold. From the cock 54- passes a second conduit 57 leading to a passage 58 in passes when the piston is to be moved backward. In the cylinder base is provided a spring valve 59 of which the spindle projects into the path of the head or neck mold halves so that when the head or neck mold is opened the valve 59 is raised from its seat in order to allow the air in front of to a second chain wheel 75 mounted upon the vertical shaft 2 and driven through toothed wheel gearing 76 from one of the two vertical driven shafts 9 and 9. In this manner the bottom molds are alternately cooled and brought-into the operative position.

The operation of the machine is the fol lowing :-At the beginning all the parts are in the osition shown in 1, 2 and 18 in whic position the head or neck mold D,

and the hand lever 33 are directed upward as shown in Fig. 1 in dotted lines: the halves of'the finishing mold A, and of the parison mold B are together and the head or neck mold, which is closed, and has the plunger projecting into the opening therein, closes the lower end of the parison mold D While the bottom mold 68 closes the lower end of the finishing mold. Glass is now supplied to the parison mold B, the operator cuts oil the glass and by operation of the hand lever 33. adjusts by means of the hand lever 56 the air cock it in such a position that compressed air passes through the bore 58 to the front side of the piston The piston is then moved backward and the rack 41 rotates the plunger 43 out of the mouth of the parison. The operator now opens the compressed air passage 53 leading to the head or neck' mold and compressed air 18 admitted through the tube 47. During the withdrawal of the plunger from the parison 7 is .now released by the pawl 8 Fig. 1; it is' raised by the action of a spring 7 and operates the inlet valve of the compressed air cylinder 3; the piston moves forward and the rack 5 by'means of the toothed wheels H rotates the vertical shafts'9 and 9 through an angle of 90 so that the finishing mold A and the pari'son mold B are opened, the latter assuming the position shown in Fig.7, thereupon the head or neck mold D with the parison together with the cylinder 31 is rotated through an angle of 180. The trip lever 7 is now depressed and by operating the valve for the compressed air the piston is moved back in the cylinder 3. The rack 5 rotates by means of the toothed wheels H, the shafts 9 and 9 into their original positions; the finishing mold A is thus closed around the parison; simultaneously the parison mold carriers 15 are also moved together whereby the connecting rods 24 rotate the three armed levers 23 carrying the halves of the parison nolds through an angle of 180 so that the parison mold Cis 'now turned into operative position and closed (Fig. 8). By pressing the hand lever 56 compressed air is admitted into the parison in the finishing mold and the parison is blown out into the form of a bottle. By releasing the lever 56 the inlet for the. compressed air is closed and the hand lever 33 is rotated upward in a plane containing the longitudinal axis of the cylinder 31 so that the two halves of the head or neck mold D are moved from one another and the neck piece is released and projects freely from the finishing mold (Fig. 20). The rear half of the head or neck mold D while opening presses against the spindle of the valve 59 in the cylinder base 52 and opens this so that the piston 39 during its forward movement does not meet with any resistance. On rotating the hand lever 33 through an angle of 180 about the longitudinal axisof the cylinder 31 the open head or neck mold is moved upward with the cylinder 31, Fig. 21, and in this movement the cylinder 31 is rotated in such a manner that the bore 50 in its cover 51 is brought into communication with the bore 49 of the air tube 47 and compressed air enters behind the piston 39 which on its forward movement again moves the plunger 43 outward to its original position. The hand lever 33 is now rotated downward through an. angle of 180 so that the head or neck mold is closed (Fig. 22)" and is new again in the original position under the cooled parlson mold6, thls is now filled with glass, the parison blown and by releasing the trip lever 7 the parison andmold 69. The head or neck mold with the parison is now again swung downward and the previous operations are repeated. By this manner of working it is possible to obtain within a certain time a larger number of bottles than it was possible with earlier machines of the same type and the quality of the goods is also superior as each mold for working the glass is at a suitable temperature. As the parison molds have time to cool very hot glass can be worked which is advantageous in the bottle blowing industry. By exchanging the bottom molds there is also the advantage (without having regard to their cooling) that the operator is independent of an assistant to remove the finished bottles and to place them in a cooling chamber. If the parison molds are of different sizes then it isipossible on a machine to alternately produce bottles of diiferent weight. If bottles .with a hollow bottom (wine bottles) are to be produced then instead of the bottom molds 68 and 69 (Fig.7)

there is provided a rotating beam 70 which is adapted to be raised and lowered and is atone end provided with a flat and at the other with a hollow bottom. The parison is blown on the flat bottom the arm is then lowered and rotated and the hollow bottom which is now under the parison is raised and forced into the bottom of the parison.
